9. Calibrating the Balance
Since electronic balances are affected by gravity gravitational acceleration, they produce different
values in various locations. Therefore, before use, balances must be calibrated at the location where
they are installed. Calibration is also required after long periods without use, or if a balance begins to
produce inaccurate values.
Calibration of a balance, or "span adjustment," is required to produce accurate measurements.
9.1 Calibration of AJ-CE Series
Applicable models: AJ-220CE, AJ-420CE, AJ-620CE, AJ-820CE, and AJ-1200CE(for AJ-
220CE.420CE, and 1200CE, applicable when the lock switch is off.)
> £ • Span adjustment should be performed with the balance installed perfectly level and without any load
on the measurement pan.
